Important Information Regarding Rechargeable Lithium Cells - LITHIUM ION (LiIon) & LITHIUM IRON PHOSPHATE (LiFePO4)

  • Single unprotected cells are available to recognised customers. For safety information please read the Lithium Battery Safety document
  • PLEASE NOTE: All lithium rechargeable cells/packs supplied by Mi Battery Engineering without a Protection Circuit Module (PCM) will require a duly signed Product Indemnity Waiver (PIW) Click here to download
  • Do not attempt to charge these batteries using chargers for nickel based batteries or any charger not specifically designed for rechargeable lithium technology.
  • This cell is manufactured for use in a battery pack assembly. It is not intended for use without a protection circuit. For equipment designed to use individual cells a protection circuit can be incorporated. MI Battery Engineering's current range of protected lithium ion cells can be viewed on this page.
  • Lithium ion cells can be assembled into single or multi-cell battery packs by authorised pack assembly centres such as our company that have been approved for safety circuit assembly and Lithium Ion pack design.
  • For information on the safety circuits, more commonly known as a PCM, please click here or follow the links to browse MI Battery Engineering's range of available PCM's for Lithium Ion and Lithium Iron Phosphate.
  • MI Battery Engineering can also provide advice and components for intelligent Battery Management System's (BMS) addtional to or incorporating PCM's. It's recommended that battery packs especially those featuring complex series/parallel cell assemblies incorporate a BMS in their construction. For further information please consult our sales engineering staff.
  • For battery pack design enquiries please contact us with your requirements. If you already have some parameters please click here for a Battery Application work sheet & email it to us.
